Compile a concise and clear summary of the assignment that involves generating, modifying, and scaling signals using LabVIEW. The task includes creating a square wave, adding a control knob for amplitude adjustment, and further scaling the amplitude by a factor of ten with a formula block. Additionally, prepare a report covering the goals, procedures, challenges, accomplishments, and conclusions related to these tasks. The assignment requires demonstrating the LabVIEW programs to the instructor and submitting a one-page typed report.

LabVIEW, developed by National Instruments, is a graphical programming platform widely utilized in engineering for designing systems that generate, analyze, and modify signals. This assignment emphasizes practical application by engaging students in creating signal generation and modification programs through LabVIEW’s visual programming interface. The core focus is on mastering the use of Virtual Instruments (VIs), which comprise the front panel for user interaction and the block diagram for system logic, enabling users to develop sophisticated signal processing applications efficiently.

The initial step involves creating a simple program that generates a square wave. This program is constructed by opening LabVIEW, selecting a new VI from the templates, and designing the front panel with controls and indicators, such as the signal output display. In the block diagram, the user employs the "Simulate Signal" VI to produce a square wave, connecting it appropriately with other components like the waveform graph to visualize the signal output. The program is executed by clicking the Run button, and the output—a square wave—is observed and verified for correctness. Students are encouraged to save this initial version as "Square.vi".

The next phase introduces interactivity by adding a Knob control to the front panel. This control allows real-time adjustment of the signal’s amplitude. The wxire connections in the block diagram are updated so that the knob’s value dynamically influences the amplitude parameter in the signal simulation VI. When the program runs, students verify that changing the knob alters the amplitude of the square wave accordingly. This step demonstrates the significance of controls and their integration into signal processing workflows.

The subsequent modification involves scaling the amplitude further by a factor of ten. Students incorporate a 'Formula' VI into the block diagram, which multiplies the original signal amplitude by 10. This is achieved by connecting the output of the "Simulate Signal" VI to the input of the "Formula" VI, setting the formula to "Signal * 10", and then wiring this scaled signal to the waveform graph. Running the program confirms the amplified output, illustrating how formula VIs can perform real-time mathematical operations on signals. The modified program is saved as "HiSquare.vi".

Throughout this process, students develop skills in visual programming, signal analysis, and control integration within LabVIEW. They learn to manipulate graphical elements, utilize signal simulation VIs, and apply mathematical functions to achieve desired signal characteristics. Demonstrating these programs to the instructor provides an opportunity to validate technical proficiency and understanding of signal processing concepts.

Finally, students prepare a succinct, one-page report in Times New Roman, size 11, with 1.5 line spacing, summarizing the goals, procedures, challenges faced, outcomes, and concluding insights. This report consolidates their practical experience, demonstrating comprehension of signal generation and scaling techniques in LabVIEW, which are foundational skills for more advanced engineering applications involving virtual instrumentation and automation.
